CFCA	SFCA	TFCA	CTCA	STCA	TTCA
The projection angle in coronal plane between the distal plane of the femoral component and the femoral force line	The projection angle in sagittal plane between the distal plane of the femoral component and the femoral force line	The projection angle in the transverse plane between the transverse axis of the femoral component and the transepicondylar line	The projection angle in coronal plane between the distal plane of the tibial component and the tibial force line	The projection angle in sagittal plane between the distal plane of the tibial component and the tibial force line	The projection angle in the transverse plane between the proximal plane of the tibial component and the tibial force line

CFCA: coronal femoral component angle SFCA:sagittal femoral component angle TFCA: transverse femoral component angle CTCA: coronal tibial component angle STCA: sagittal tibial component angle TTCA: transverse tibial component angle.
